A difficult secondary use (farming) could result from a high density of small VAWT.
In the other hand perhaps VAWT could be interesting if some structural features are studied to reach scaling more than any HAWT while the implementation is facilitated, above all offshore.
See below the available publication confirming some favorable structural features:

I have maybe some structural ideas for large VAWT offshore, in combination with some other quoted elements above.
